There are times when the camera’s digital sensor cannot record the whole range of light tones in the image. There will be either under or over-exposure. There are two ways around this problem. Sometimes an ND graduated filter can be used. It’s not always possible to use an ND grad though. This is where the HDR technique comes into its own. In this lesson I will explain how to take the images required to produce an HDR image and then look at the post-production computer part of the technique. This lesson will give you much greater flexibility when it comes to achieving the correct exposure of your image in challenging lighting conditions.
